Application filed February 11, 1907, Serial No. 356,790. Renewed October7, 1907. Serial No. 896,327.

To all whom it may concern.

Be it known that I, Riemann FjDowNEr, a citizen of the United States,and resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inAnticreeping Devices for Rails; and I do hereby declare that thefollowin is a full, clear, and exact description thereo The inventionconsists in certain peculiari--- ties of construction and combination ofparts. as hereinafter descnbed with reference to the accompanyingdrawings and subsequently claimed, its ob3ect be ng to provide s mple,economical and effective means for the prevention of rail-creeping.

In the drawings: Figure-1 represents a cross-section of a portion of arailway mil with an anti-creeping rail-bracket embodying the features ofmy invention in position thereon; Fig. '2, a similar view showing thebracket in position to be adjusted to the rail; Fig. 3, an elevation ofthe same in position on a rail, with parts broken away and parts insection to better illustrate the details, and Fig. 4, a detached planview of said bracket.

Referring by letter to the drawings, A indicates a rail-fiange havingsecured thereto,

a metallic bracket B. The body-portion of the bracket consists of astrap having a hookand C, which end grips one edge of the railflange,whi] e an upturned nose D at the opposite end of said bracket serves togrip the adjacent rail-flange edge. I The bracket has a dey pending wingE, that abuts against the side 'of the tie and thereby prevents the railfrom creeping.

In practice, the distance between the throat of the hook G and innerface of the nose D is slightly less than the width between edges-of therail-flange. In order to fit the bracket to a rail-flange, it is firstsubjected to heat sufficient to expand the same, the bracket being thenapplied by, means of suitable tongs. The hook-end is first adjusted toone end of the rail-flange "(as shown in Fig. 2) and the nose thereafterpressed over the opposite edge. By the above method the bracket, whencooled, will be firmly shrunk upon the rail in the desired position, andconsequently after cooling becomes practically a part of SZIIdT rail,the result of which is an absolute'clieck against slipping of thebracketnpon said rail when the lattcr .,is subjected to a creeping Theabove described arrangement dispenses with all bolts, etc.,which arecommon to this class of device, and thereby not only greatly reduces thecost in manufacture, but also saves time in adjusting the anti-creepers,thus providing a single clamping memher that will accomplish the desiredresult,

which heretofore required three or more separate parts.

If desired, when the heated bracket is first aflixed to the rail; itsnose may be slightly struck over the edge of the rail, by a hammer-blow,in order to make the contact more bracket, it is u derstood that it iswithin the 70 I perfect, and wzile I have shown one form of scope of myinvention to vary the same indefinitely, the essential featureconsisting of a metallic clamping-member adapted to be subjected to heatand thereafter shrunk upon a rail for the purpose specified.

While, for efiicient holding power, I consider that the clamping memberought to be shrunk upon the base flange of the rail by the use of heatas above described, it may well be that under some conditions it may besufi'iciently shrunk, clamped or gripped upon the rail by a mere bendingof the ends of the clamp over the rail flange. under suficient pressure.It is obvious that whether the clamp is sufiiciently contracted upon therail flange by heating and cooling, or by'heating, applying bendingpressure and then cooling, or by simply applying suli'icient bendingpressure npop the clamping ends of the devices are matters relatingmerely to the manner of assembling the parts, the assembled combinationbroadly embodying my invention and being essentially the same whicheverprocedure is followed.

2. An anti rail-creeping device comprising a single member adapted to beshrunk upon a rail-flange.

3. An anti rail-creeping device rail-flange engaging-ends the' distancebe tween the ends beingenormally of less dimension than th -width of therail-flange, and adapted-to be shrunk on said rail-flange.
